T0 all 'whom t may concern Be it known that I, CHARLES K. RICE, a citizen of lthe United States, residing at Indianapolis, in the county of Marion and ,State of Indiana, have invented a new and useful Heating-Stove, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to stoves, furnaces or the like in which fuel is consumed for producing heat for various purposes, the invention having reference more particularly to the fuel combustion features thereof.

An object of the invention is to provide an improved stove that shall be so constructed as to be highly eiiicient in supplying heat economically.

A further object is to provide a simple and cheaply constructed stove which in operation shall draw in and heat the cooler air on the floor of an apartment and thereby facilitate the heating of the air throughout the compartment.

A still further object of the invention is to provide a stove adapted for supplying warm air to the top of the fire in order to insure the most complete and economical consumption of the fuel required for producing the heat.

With the above mentioned and other objects in view, the invention consists in a stove having certain novel features of construction whereby the objects of the invention are practically attained; the invention consisting further in the novel parts and combinations and arrangements of parts as hereinafter particularly described and further deiined in the accompanying claims.

vReferring to the drawings, Figure 1 is a front elevation of the improved stove or furnace partially broken away to expose internal portions thereof; Fig. 2 is a vertical section approximately on the line A A in Fig. l; Fig. 3 is a horizontal section approximately on the line B B in Fig. 2; Fig. 4 is a fragmentary section on the line C C in Fig. 2; Fig. 5 is a sectional elevation approximately on the line D D in Fig. 2; Fig. 6 is a horizontal section on the line E E in Fig. 2 looking upward; Fig. 7 is a fragmentary section on the line F F in Fig. 2; Fig. 8 is a perspective view of the internal 7 structure of the stove; Fig. 9 is a rear eleval tion of the structure; and Fig. 10 is an inverted plan view of a part of the structure.

Similar reference characters in the several figures of the drawings indicate like parts or features of construction herein referred to.

In the preferred form of construction of the invention with respect to a stove suitable for heating purposes generally,a base flange 1 is provided which preferably has supporting legs 2, the iange extending from a plate 3 that constitutes the bottom of the ash-pit required in coal burning stoves, the pit having a front 4, a back 5 and sides 6 and 7 and also an apertured top 8 on which a fire grate 9 is supported. An air duct is formed under the bottom 3 by means of wings 10 and 11 connected to the under side of the bottom, and a bottom plate 12 connected to the wings so that the duct extends from the front to the rear portion of the flange 1, the front portion having apertures 13 therein to admit cool air into the air duct, the air admission being regulated or prevented when desired by means of a regulator 14 mounted on the front portion of the flange so as to close or partially close the apertures 13. The front 4v of the ash-pit is provided with a door 15 having an air inlet regulator 16 therein for governing the admission of air through the lire grate. A section of air duct is formed behind the ash-pit by means of a back wall 17 extending upward from the base flange and having side walls 18 and 19 thereon that are connected to the back 5 of the ash-pit. A fire bowl or pot 2O is seated upon the top 8 so as to extend about the fire grate, and the bowl has an air duct section on its rear portion that is formed by side walls 21 and 22 connected to the bowl and an outer plate 23 connected to the sides, the duct continuing from the duct that is behind the ash-pit that continues from the duct that is under the ash-pit. The stove comprises also a drum or body portion 24 seated on the bowl and having a fire door 25 on its front portion, the door having apertures 26 therein that may be closed or partially closed by a regulator 27 mounted on the door. The drum has an air conduit section on the rear portion thereof formed by wings or side walls 28 and 29 connected to the wall of the drum and an outer plate or wall 30 connected to the wings, the duct continuing upward from the duct at the rear of the fire bowl. The upper rear portion of the wall of the drum has tion with the duct'which has a top 32 that is connected with the wall of the drum above the aperture and is connected also to the walls 2S and 29 and to thewall 30, the latter having apertures 33 therein that may be closed or partially closed by a regulator 34 having apertures 35 therein and movably mounted on the wall 30. The rear portion of the wall of the drum has a cleaning hole 36 therein above the aperture 31 and it is normally covered by a gravity shutter 37 hung on the wall.l A top 38 is secured to the top of therdrum and it has a flue hole 39 therein adjacent to the rear portion of the drum and provided with a flange 40 to which a draft pipe 41 is connected.

Y The combustion chamber ofthe stove yis provided with a partition which serves the purpose of a baiile plate, a deflector and a heat radiating plate or wall for heating air and also for radiating heat above the lire to promote combustion, and it' comprises an approximately upright portion 42 that is arranged opposite to the rear wall portion ofthe drum at a short distance therefrom, and it has a forwardly curved portion 43, all being fluted so as to have ribs 44 on the rearward and upward side thereof, this being preferable in order to present the maximum radiating area to the air passing between the plate and the wall of the drum. The lower end of the upright portion 42 terminates at a suitable distance above the level at which the fuel is to be maintained, and it has downwardly projecting fingers 45 thereon to prevent the fuel from choking the air passage but permitting the air to pass between the fingers above the fuel. The upper portion of the partition has side portions 46 and 47 that extend to the wall of the drum, and the rear edges 48 and 49 thereof coincide with the edges of the upright portion 42 so as to form a joint with the wall of the drum, said joint edges having screw holes 50 and 51 therein respectively that receive screws 52 and 53 inserted through the drum wall to secure the partition to the drum and thus form an air passage which is partially formed by a bottomless box-like structure connected to the top of the partition and comprising a front wall or plate 54 connected to and extending upward from the forward edge of the portion 43 of the partition, and side .walls55 and 56 extending from the wall 54 back vto the rear portion of the wall of the drum at opposite sides of the aperture 31, the side walls having base extensions 57 and 58 thereon respectively that are secured to the sides 46 and 47. An approximately horizontal partition plate 59 extends from the rear portion of the drum wall below the aperture 31 and forward toward but notentirely usual.

tendingupward from the rear portion of the drum wall, and'itpreferably is cast integrally with the walls 54, 55 and 56 at a suitable distance below the plane of the top thereof. The sides 55 and56 have ears 60 and 61 thereon respectively that` are secured to the wall of thedrum 24. A top plate 62 is secured to the walls 54, 55 and 56 and it is suitably curved or formed so that its edges fit closely against the inner side of the wall of the drum, Vto constitute the top of an air passage extending from the aperture 31 and which preferably is divided by partitions 63, 63 cast integrally on the top 62and extending down to the partition plate 59, the partitions extending radially from the aperture 31 so that the incoming air is spread out opposite the front 54 to pass downward under the partition plate 59 and thence to the fire bowl. The top 62 is arranged at a suitable distance below the top 38 of the combustion chamber so that the gases of combustion or smoke must pass over the top 62 on their way to the draft pipe; and since ashes or soot may be deposited upon the top 62 the saine may be removed by a scraper inserted through the cleaning hole 36. Y

In practical use bituminous coal or coke preferably is used as a matter of economy and the fire bowl should be approximately full of fuel at all times, a proper amount of air being admitted through the grates as usual to maintain combustion, the intensity of the fire, however, being regulated as lnvsome cases the regulator 14 may be closed when starting a lire and the regulator 34 may be opened, but preferably the latter should be closed when the stove is operating normally, the regulator 14 being opened to permit atmospheric air to pass through the conduit to become slightly heated in the lower portion of the conduit and further heated on its way up to the aperture 31, the air passing thence forward over the plate 59 and then below the plate where the air becomes heated to a high degree by the forward portion 43 and the upright portion 42 of the partition as the air passes down upon the fire, the heated air mixing with the product of more or less imperfect combustion and aiding to produce more perfect combustion of the gases thrown off from the fire, the combustion being further promotedbyfthe heatradiated from ythe front of the fiuted partition so that a high degree of economy is attained while the wall of the drum and the top radiates the heat developed as usual. v
